The parts are held together and secured to the wall by a series of screws 18, engaged with the strip 15, and passing through the strip 14 into the wall. This construction provides for a jamb adjustment to accommodate for variations in door width opening and to properly fit the door to the jambs, as the j amb 15 can be set to the perpendicular or at any inclination thereto.

The strip 15 at its outer edge is provided with an angle extension 19 for anchoring a rubber or pliable packin strip 13 serving as a stop or buffer for the oor.

Having described my invention, I claim:

1. An adjustable door jamb, comprising, a pair of channel strips with the channels thereof opposing each other, and one strip telescoped within the other to rovide a hollow unit, a series of springs interposed be-' tween said strips and housed thereby for urging the strips apart, studs within the channels fixed to one of the strips, each respectively supporting a spring, and fastening devices passing through said strips and studs and into the wall to which the jamb is secured and relatively. adjusting said strips. 2. An adjustable door jamb, comprising, a pair of channel strips with the channels thereof opposing each other, the strips telescoped to provide ahollow unit, one of the strips having a lateral flange longitudinally thereof formin an abutment for the free edge of a hinge oor, a series of springs interposed between said strips and housed thereby or urging the strips apart, studs within the channels fixed to one of the strips, each respectively supporting a sprin and fastening devices engaged through t 1e studs, adjustably securing said strips together and securing the parts to the walls of the door opening.
